AUTOMATIC PRESSURE-TANK.

I Specification of Letters Patent.

Patented Aug. 7, 1917.

Application filed September 18, 1913, Serial No. 790,421. Renewed July 9, 1917. Serial No. 179,574.

To all whom it may concern Be it known that I, ARTHUR G. -HIOKS,' a citizen of the United States, and a resident of Sargents, in the county of Saguache and State of Colorado, have invented a new and Improved Automatic Pressure-Tank, of which the following is a full, clear, and exact description.

This invention relates to steam boilers and has particular reference to devices of this kind adapted particularly for household use, though as to the particular purpose or adaptation I do not wish to be unnecessarily limited.

Among the objects of the invention is to devise a boiler with specially arranged connections whereby steam pressure within the boiler may be utilized in a new way to suck or draw water from a well or other source of supply and deliver the same either to the boiler to replenish the supply thereof or to any other place for use. i

A further object of the invention is to provide a household boiler adapted to deliver either hot or cold water from a well of cold water.

A still further object of the invention is to arrange the water supply for a bathroom or the like in such a Way that water may be delivered to the bathtub either hot or cold or at any intermediate temperature.

The foregoing, and other objects of the invention will be hereinafter more fully described and claimed and illustrated in the drawing forming a part of this specification in which the figure is a vertical section of a boiler equipped with my improvements, certain of the parts being shown in elevation.

. From what has been stated above, it will be understood that the several parts of the device may be made of any suitable materials and the location thereof may be varied also to a certain extent with relation to one another without departing from the spirit of the invention hereinafter more fully set forth and specifically claimed.

At 10 I show whatlmay be regarded asan ordinary form of domestic boiler suitably supported upon a stand or tripod 11. The numeral 12 indicates a heater such as a cooking stove or range provided with a heating coil or water back 13 having connections with the boiler. A pipe 14 leads from the bottom of the boiler into the water back and the pipe 15 leads from the upper portion of the water back through the top of the boiler. The several pipes will, of course, be connected with the several water chambers by means of suitably packed joints. The connections, however, at 16 with the top of the boiler includes a pipe 17 extending from the top of the boiler to a point adjacent the bottom thereof and having a detachable filling plug 18 for the ini tial filling of the boiler. The boiler also is preferably equipped with a steam gage 19 and a safety valve 20 each having its usual functions.

At 21 I employ a well known type of inspirator, the same, however, being particularly adapted or reconstructed for my pres ent uses. This inspirator is connected to the end 14 of the pipe 1 1 on the opposite side of the boiler from the heater. That portion of the pipe indicated as 14 is also provided witha check valve 23 and a globe valve 22. The check valve is arranged to open toward the boiler and prevents steam from forcing water through the pipe toward the inspirator, and the globe valve is adapted to completely close the pipe 14; under certain conditions. A steam pipe 2% eX- tends from the top or steam space of the boiler down to the inspirator and this pipe is fitted with a globe valve 25.

To the lower portion of the inspirator is connected a suction pipe 26 leading from a well W or other source of supply. A discharge or overflow pipe 27 is connected to another portion of the inspirator and is provided with a globe valve 28.

The inspirator is provided with two stop cocks 29 and 30 either of which may be open while the other is closed, or both may be partially open at the same time, according to the result desired or the conditions with which the operation is carried on.

Having thus briefly set forth the construction, its methodof operation may be described as follows:

Water first being supplied to the boiler to a point substantially midway of the gage glass 31 through the filling'pi iie '17, the

water back 13 will consequently be filled at the same time. Upon starting the fire in the heater, the water therein will become heated, forming steam in the steam space of the boiler. When the pressure gage indicates sufficient pressure according to the work to be accomplished, the globe valve 25 in the steam pipe 24 will be opened. If

cold water is desired to be delivered from the discharge pipe 27, the valves 28 and 30 will be opened. Stea1n,-tl1erefore, will be forced through the inspirator, passing from the barrel 32 thereof through the neck 33' and directly through the valve 30. This steam will, of course; be delivered with the water, butbeing in a comparatively small quantity with respect to the water delivered, the water will! not be excessively heated If, however, hot water is to be delivered from the deliver-ywpipe 27, the valve 80 will be closed, and the valve29 opened,which will cause the course of: the steam to be from the barrel 32 through the neck 8% and valve 29, the quantity of steam in'this case being much greater in proportion to-the amount of water, itwould serve to heat the water passing-through the inspiratora The=water delivered; therefore, will be hot; Again, if the supply of water in the'boiler becomes low, the valve 28 will be closed and the globe valve 23=will be opened which will havewtheeflect of causing; the inspire-tor to automaticallyreplenish the supply of water which will passthrough the 'tubeisection 14*! and bedelivered into the boiler through a series-50f perforations-14 of-the tube 14:, the WtLtBIrlIk this case beingalso de livered into theboiler 10 hot, with the valves; of' the inspirator arranged as just described.

By; means of the construction and arrangement herein shown, water'can be forced inany direction as wellzasbeing elevated, and thetemperature ofthe. water may be varied I at will according, to i the control of the relative amounts of steam and water caused to pass through the-inspirator, or, in other words, according to the various positions of: thevalves' 29' and 30." With this apparatus, h-ot' andco'ld water may be elevated to abathroom or for any other purpose for which hotr or= cold water' may be needed. The device can also be used-in con-- nection with city water supply or'in connection with' any othergbody of water, thus eliminating the necessity for having astorage tank supplying fresh water:

Having thus described my invention, I claimkas new and desirevto secure byLet ters Batent=':-

1.. The combination with a= water'back of a stove, of. a pipe having communication with the water back and having. a portion projecting outwardly from the water back,
